Abstract: In this paper, the stochastic model of the communication system of a communications satellite in the fading channel is given under the random service request and random energy harvesting. The problem of maximum throughput based on event-driven TPR control is presented. The stochastic communication model system is transformed into a hybrid-state Markov decision processes with finite action sets, the existence of the optimal stationary policy is illustrated and the optimal TPR algorithm is proposed. Finally, a numerical example of event-driven TPR is presented to illustrate the theoretical result, and the influences of system parameters on performance are also investigated. This study has a positive significance to the communication design and management, resource allocation optimization and sustainable development of communication satellites.

Key words: satellite communications, optimal control, transmission power rate, Markov decision process
